In the present study, the conservative integral formulation is developed for calculated the intensity of singularity at a vertex of the interface in three-dimensional piezoelectric dissimilar material joints. The model applied mechanical load is considered. In order to investigate the influence of integral area on the accuracy of the results, models with various integral areas are used. Finally, distributions of stresses are compared with the FEM results, in which using a model with extremely refined meshes near the singular point.
